My invention relates to washing devices and has for its ob'ject toattach washing machine elements to an ordinary tub to constitute' awashing machine, to provide manually operable washing machine elements,to manually reciprocate vacuum cups supported above a tub, and to rotatethe'vacuum cups automatically when the cups are reciprocated. Inaccomplishing these and other objects the invention Thav'e'providedimproved details of structure, the referred forms of which areillustrated inthe accompanying drawings, wherein:

Fig. 1 is a perspective view of my inventipn installed on a tub. 7

Fig. 2 1s a detail perspective view of a vacuum cup rotating mechanism,having a ratchet-engaging 'awl latched in retracted position, the'cup'support'ing rod being shown fragmentarily and a supporting bracketarm in section. i l

' Fig. 3 is a detail perspective View of a rodsupporting frame andoperating arm, the rod being shown fragmentarily.

Fig. 4 is a perspective view of a modified form of mounting meansillustrating the si'ipporting bracket adapted for associating thedevicew'itha bench provided with two tubs.

'Fig. 5 is a perspective view of the bracket supporting benchand'modi'fied bracket in collapsed position. I I i Fig. 6 is a viewsimilar to that of Fig. 2, but showing the pawl in normalratchet-engaging position. V

Referring in detail to the drawings 1 designates a supporting bracketcomprising a base member'2 adapted for positioning on the rim 3 of atulo l adjacent one edge thereof. 5 is a vertical Wringer-supportingmember over which a yoke 6 extends, the legs 7 of the'yo'ke beingengaged with the base member 2. 3' i Rods 8 extending through thevertical member 5 have hooks 9 at their lower ends engageable under" thelower rim 10 of the tub whereby the support may besecurely engaged 'withthe tub by tightening nuts 11 onthe upper ends 'of the'rods. Reinforcingstrips 12 overlie the upper edge of the vertical member 5, interposedbetween the nuts 11 and the member,the inner endsof the strips 12 being"spaced to provid'e'aslot 13 to admit the outer end 14: of a frame arm 15to the cross member of the yoke 6, and

a retaining strip 16 overlies the slot 13 to ret'ain the arm on theyoke. The retaining strip is removably secured to the bracket member 5by bolts 17 extending through the strips 12 and into the member 5, andthumb screws 18 on the outer ends of the bolts.

The structure described is provided for supporting a skeleton frame 19and a vacuum cup bridge 20 above thetub/ The bridge 20 is fixed by amanually oper-ablesCreW 21 to the lower end of a spindle rod or shaft22, which is slidably and rotatably movable in the frame, as presentlydescribed, whereby vacuum cups 23 fixed to the outer ends of the bridge20 may be moved vertically into an: out of the tub and may be rotatedfor posit-i'on-ing the cups in varying relation to' the contents of thetub.

The frame 19 comprises the aforesaid outer frame arm 15, a vertical post24 spaced from the outer end of the arm, and a second arm 25 parallelwith saidarm'l5 and projecting from the upper end of the post 2 1, anintermediate reinforcing web 26 extending from arm to arm beingpreferably provided for adding rigidity to the structure. The actuatingand supporting rod' 22 extends through the outer end of the frame armand also rotatably through an opening 27 in the outer end of thesupplemental arm 25 and is yieldingly supported in elevated position bya lever 28 pivoted in an ear 29 extending rearwardly from the post 24and a link 30 pivotally connected with the lever adjacent its outerend',"the link having a'perforate lateral flange 31in which the upperend of the rod is rotatably extended. A nut '32 supports the link fromthe rod and aknob-like handle 33 fixed in the end of the rod isrotatable over said flange, a spring 34 having one end 35 fixed to thecross arm 25 and its oppositeend secured to an ear "36 on the lever 28urging the link to lift the rod into upwardly extended position. Ahandle 37 is provided on the outer end of the lever 28 whereby the rodmay be reciprocated to urge the vacuum cups into contact with thecontents of the tub, While the cups, rod and handle may be returned toelevated position by the spring 34.

I further and preferably provide means for automatic rotation of thevacuum cups upon reciprocation of the rod comprising a ratchet wheel 38fixed to the rod above the bridge and below the frame arm, havingslantingly positioned arcuate teeth or blades 39 and a pawl 40 pivotallymounted in lugs 41 on the frame arm for swinging in clock wisedirection, and beingstopped by the frame arm 15 for normally engagingthe blades 39 of the wheel when the rod is elevated, whereby engagementof the blades with the pawl will cause the rod to move rotatably.Referring to 6, the pawl engages one blade 39 of the upwardly movingratchet-wheel to cause the rod to turn, and

.the adjacent blade 39 of the repositioned downwardly moving wheelengages the pawl and pivots it outwardly, the pawl then returningautomatically to blade-engaging position. A horizontally movable latch43 is pivoted on the frame arm adjacent the pawl to engage under a hookend 44 of the pawl for restraining the sameaway from the bladeengagingposition when it is desirable to dispense with the service of the pawl.The hook may also serve to urge the pawl to swing in clockwisedirection. A boss-like shoulder 41 may be provided between the lugs 41,for example on the frame arm, to limit the pivoting of the pawl ineither direction, and preferably when the lower edge of the frame arm 15would not stop the pawl in desired position to engage the blades. J

In the modified form of the supporting bracket shown in Fig. 4, thevertical spacing member 5 is secured to vertical posts 45 sup ported bya collapsible Joench 46 comprising longitudinal frame members 47 towhich leg members 48 are pivotally connected, whereby the end 14 of theframe arm 15 may be inserted from one or another side of the supportingbracket to associate the vacuum cups and operating mechanism with one oranother of the tubs that may be positioned o the similar portions of thebench.

In using the device, the supporting bracket is associated suitably witha tub for supporting the frame and rod abovevthe contents thereof, thespring supporting the vacuum cups in elevated position; The cups aremoved into contact with the contents by downward pressure on the leverhandle, and the -spring assists in returning the cups to elevatedposition:

Q'Ihe left hand of the operator may 'grasp the rod knob to rotate therod to reposition the cups in relationto the contents,while the cups arein elevated position, and the pressure of the left hand on the rodpromotes the desired effect of the cups on the materials being washed,the pawl which is pivoted on the frame being latched in retractedposition for manual rotation of the rod. The pawl may be unlatched andwill then engage the ratchet upon each upward movement of the cups tocause a partial rotation of the rod and cups.

What I claim and desire to secure by Letters Patent is: v r s 1.
